> This is a tech debt worth cleaning up: KStreamWindowReduce should be able to be replaced by KStreamWindowAggregate. In fact, we have already done this for session windows, where in {{SessionWindowedKStreamImpl}} we use {{reduceInitializer}}, {{aggregatorForReducer}} and {{mergerForAggregator}} to replace reducer with aggregator.
